Abstract

The embodiment of the invention discloses a data synchronization method, a device, equipment and a storage medium. The method comprises steps: recording information of the incremental operation through an auxiliary table, wherein the information of the incremental operation includes a type of the incremental operation and a row number of a row table corresponding to the incremental operation, or includes a type of the incremental operation and a row number and a column number of a row table corresponding to the incremental operation; determining incremental data in the row table according to the incremental operation information, and synchronizing the incremental data into a list. The embodiment of the invention can improve the efficiency of data synchronization.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of data synchronization, and in particular, to a data synchronization method, device, device, and storage medium. Background technique [0002] Row storage table (referred to as row table) and column storage table (referred to as list) are different in their data storage and management methods, resulting in their own advantages and disadvantages when performing different operations. Among them, the addition, deletion, and modification operations (INSERT\DELETE\UPDATE) of the row table have better performance, and the query operation (SELECT) of the list has better performance. [0003] In practical applications, you can use a row table to manage data, and use a list to analyze data at the same time. The specific method is to create a row table first, which can directly add, delete, and modify the row table; then create a list, and every time you analyze the data, you need to query all ...
